Key Features & Benefits at a Glance
- Superior corrosion resistance with black-oxide coating, extending service life in demanding industrial environments.
- Exceptional thread precision with Class 3A fit, ensuring reliable, vibration-resistant fastening in critical assemblies.
- High-strength durability from Rockwell C45 hardened alloy steel, preventing stripping and deformation under heavy loads.
- Secure, flush mounting with headless design and cup tip, minimizing protrusion while maximizing grip on shafts and components.
- Efficient installation and removal using the 5/32" hex drive, allowing high-torque application in confined spaces.
- Optimized for fine-thread applications with 5/16"-24 UNF right-hand thread, providing enhanced adjustment accuracy and load distribution.
- Full regulatory compliance with ASME B18.3, RoHS 3, and REACH, ensuring safety and environmental standards are met.
Professional Applications & Engineering Value
This black-oxide alloy steel set screw is engineered to address common industrial challenges such as component slippage, corrosion-induced failure, and assembly inaccessibility. The Class 3A UNF fine thread delivers tight tolerances for precise axial positioning in machinery, automotive, and aerospace systems, while the cup tip design bites securely into shafts or collars to resist rotational forces. The headless, hex drive configuration allows installation in tight spaces without compromising torque transmission, making it ideal for permanent or semi-permanent fastening in high-vibration environments. Combined with Rockwell C45 hardness, it ensures long-term reliability in heavy-duty applications where fastener integrity is critical.
Specification Summary & Compliance
This set screw features a 5/16"-24 UNF fine thread with Class 3A fit for high precision, a length of 5/8", and a 5/32" hex drive. It is manufactured in compliance with ASME B18.3 specifications and meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental standards, ensuring both performance consistency and regulatory adherence for industrial use.
